The Duchess With an Empty Soul

The naïve Yvona is ready to do anything for her amazing fiancé! Summon magical beasts and let him take the glory? Sure! Wreck her body for a powerful spell and die for him? Yes! Watch him secretly embrace her trusted cousin Tristan with passion and deride her openly? Oka— wait. What? Just then, Yvona dies... and wakes up a year in the past with a burdened heart. Armed with her knowledge, Yvona's ready to fight for herself. And hmm, maybe form an alliance with the coldhearted Duke of Azentine... --- I died miserably on the day I found out the truth. The truth that my fiancé had a hidden lover, and it was my very own male cousin. On the second morning, after my 20th birthday, a miracle happened. From that point on, I decided not to believe in love anymore. I want to have a relationship with no strings attached and without any superficial feelings such as love. "Duke Agentine, will you marry me?" This proposal was nothing more than a marriage to keep up appearances and without love involved.
